Just tested mine in Google maps. Locks immediately, and my location is quite accurate. I also updated the firmware.

What is your damn point, we are trying to see if gps is working, not buy routing software.

I tried mine earlier today, and it wouldn't connect to gps via google maps, however as soon as I downloaded GPS Essentials it started locking onto satellites. I think there are still some issues with it though, because the most accurate reading I could get was within 80 meters, which sucks royally. I'm going to contact Asus tomorrow and ask them about it.

I totally saw this coming ever since the WiFi issue became apparent. It's the metal body, it won't lock on to GPS. They did not think this through at all. Thankfully GPS is not that huge an issue compared to WiFi, but it is still a major thing to a lot of users, especially when using it as a navigation tool in cars or for location based services.

this really sucks

I just found out now that I can pick up my prime at gamestop and this is holding me back. I need more tests than 5 people with 3nos and 2yeses.

Yeah they definitely failed at trying to copy ipad 2 with the metal body thing. One thing apple did was use their heads when making the metal case by adding a plastic apple logo to the back of the device and having the wifi antenna right behind it so that it gets good signals lol.

I dont think they will be able to ever fix it, but maybe if you send it back to them they can add another GPS antenna?

Do you guys honestly think Asus designed a device with non functional GPS? The wifi issue was a manufacturing defect, nothing to do with the metal back.

Actually if you do your research, its not a defect. It has everything to do with the metal case. They recalled them and installed a second wifi antenna to help remedy the problem but its still weaker than TF101 according to reviews that did in-depth testing for this.

Actually the problem was the second antenna wasn't working. They didn't install a new antenna, it was already there.

Oh. My....

Yeah they just slapped a second wifi antenna in there.

    I felt compelled to register and post because I see a lot of misinformation here. Let's get a few facts straight...

    -GPS does not require the use of a WiFi(802.11) or cellular(2G/3G/4G) connection to get a first fix
    -Some implementations of GPS have the capability to use WiFi and/or cellular connections as an option to help speed up time to first fix. This is called AGPS and only affects time to first fix.
    -Accuracy of GPS typically does not increase with WiFi or cellular connection. In other words, once a fix is obtained, GPS accuracy is the same whether WiFi or cellular connections are present. I say typically though because there are some advanced systems that use off device servers to do some heavy computations and then relay device location back to the device through WiFi or cellular. I doubt this is the case with the TF201.
    -Some devices have no GPS and just use WiFi or cellular data to provide a very rough (e.g. 200m) location accuracy. THIS IS NOT GPS.

    I believe the TF201 has a GPS system that uses WiFi to help speed up time to first fix. That said, WiFi should not be required in the TF201 when trying to get a first fix, and the lack of WiFi should only extend the time to first fix.

    Given the symptoms people are reporting, and the fact that it is not consistent from device to device, I also believe the problem plaguing the TF201 is hardware related and specifically related to the GPS's receive sensitivity. Perhaps there is some variation in antenna impedance from tablet to tablet. This could be caused by something as trivial and devastating such as manufacturing intolerances that cause the aluminum metal casing to inadvertently touch an antenna and screw up the receive path impedance.

    So I just got my replacement ATP. Before I took the first one I got back to
    Best buy I shot a comparison video for the GPS. The Second one I got has a
    working GPS. Its not as strong as it should be but its working. The first one..
    nothing.

    Both on my car hood in my driveway on a clear night with full view of the sky.
    It took about 1 minute for the one with a working gps to get any signal. The
    signal strenth seemed to fluctuate a lot.

    Who'd listen to you? You're an idiot. :)

    I suggest people trying to get a fix without holding the tablet. Try laying it on its face and back and see if you can get a fix.

    Hello fellow members. I know this is not a fix but a workaround to have navigation working assuming you have a smartphone with bluetooth tethering .

    I have the transformer prime nonrooted and evo 4g running cm7.1.

    I used this how to video

    http://m.youtube.com/#/watch?desktop_uri=/watch?v=d43uq-gzI_I&v=d43uq-gzI_I&gl=US

    I first blutooth tether to get internet access. Uses less battery. (I didnt follow his wifi tethering instructions )

    Make phone discoverable connect tablet. Hit pair on both devices, then connect internet on tablet bluetooth setting ( once done i turn off discoverable on phone)

    Then enable the phones gps app (gps over bt, market free )left discoverable at 30. (I change this to 5 still works fine)

    On the tablet i went to settings application setting enable mock location

    I then launched the tablet gps app (bluetooth gps, market free by googoo ) and enable mock location. Then hit the connect button. And thats it.

    Add the widget tablet. Done.

    Hopefully ics does fix this problem

    I love my evo 4g with cm7. Does everthing i need
